FAQ

What is pultrusion?

Pultrusion is a continuous manufacturing process where fibres and resin are pulled through a hot shaping die, then cooled at the other end. Although a range of fibre types & matrix resins can be used to produce composites, the majority of applications employ fibreglass (using polyester resins) or carbon fibre (using vinylester resins).

What colours can I have?

GRP:
White or black GRP products are generally kept in stock (up to 10mm diameter for rods and up to 12.7mm for tubes in both colours). The larger sizes of both products are available in white. Other colours can be produced in GRP, with a minimum order value per product of £500 excluding VAT.

Carbon:
Is always black.

What lengths do the products come in?

Our products are manufactured in either 3 metre or 5 metre lengths. If you would like goods cut to specific lengths out of the stock lengths, please call us for a quotation on 01923 726950.

How do I cut it?

For frequent users a diamond blade circular saw is best. For small quantities use a junior hacksaw or a fine-toothed hacksaw blade (32 tpi). Tip: When using a hacksaw, tape around at the point to be cut and cut through the tape. This will help to prevent fraying.

GRP is glassfibre reinforced plastic, FRP is fibre reinforced plastic. They are the same product, just different terminology. FRP is primarily used as the abbreviation in the USA.

What is the difference between GRP & carbon?

GRP is strong, versatile, lightweight and economic. Carbon fibre is lighter and stiffer than GRP of the same size. All pultruded products have a memory - ie when bent and released, they will return to their original shape.

Do I need a rod or a tube?

Rods are more flexible, will withstand greater bending and are crush resistant. Tubes are stiffer and lighter, and best used for applications where little curvature is required.

Do you supply anything other than rods, tubes or strip?

Yes, we can supply other profiles, eg angles, channels, square tubes etc. Please call us for details on 01923 726952.
